Abstract

A modeling method performed for a cell site to detect changes in or at the cell site includes obtaining first data regarding the cell site from a first audit performed using one or more data acquisition techniques and obtaining second data regarding the cell site from a second audit performed using the one or more data acquisition techniques, wherein the second audit is performed at a different time than the first audit; processing the first data to define a first model of the cell site using the associated one or more location identifiers and processing the second data to define a second model of the cell site using the associated one or more location identifiers; comparing the first model with the second model to identify the changes in or at the cell site; and performing one or more actions based on the identified changes.

Claims

1. A modeling method performed for a cell site to detect changes in or at the cell site, the modeling method comprising:

obtaining first data regarding the cell site from a first audit performed using one or more data acquisition techniques and obtaining second data regarding the cell site from a second audit performed using the one or more data acquisition, wherein the second audit is performed at a different time than the first audit, wherein the one or more data acquisition comprise using an Unmanned Aerial Vehicle (UAV) to fly about the cell site to capture the first data in a first flight and the second data in a second flight which is at the different time from the first flight, and wherein the UAV is constrained in each flight to capture the first data and the second data by utilizing a zone indicator on the ground at the cell site to launch from a same location and same orientation in both the first flight and the second flight, wherein the orientation defines which direction the UAV is facing at launch and landing, and wherein the first data and the second data each comprise one or more location identifiers associated therewith;

processing the first data to define a first model of the cell site using the associated one or more location identifiers and processing the second data to define a second model of the cell site using the associated one or more location identifiers;

comparing the first model with the second model to identify the changes in or at the cell site; and

performing one or more actions based on the identified changes comprising maintenance to correct the identified changes.

2. The modeling method of claim 1, wherein the identified changes are associated with cell site components installed on a cell tower at the cell site, and wherein the one or more actions comprises any of maintenance, licensing with operators, and removal.

3. The modeling method of claim 1, wherein the identified changes are associated with physical surroundings of the cell site.

4. The modeling method of claim 3, wherein the identified changes comprise any of degradation of gravel roads, trees obstructing a cell tower, physical hazards at the cell site, and mechanical issues with the cell tower or a shelter at the cell site.

5. The modeling method of claim 1, wherein the first data and the second data are obtained remotely, without a tower climb.

6. The modeling method of claim 1, wherein the first model and the second model each comprise a three-dimensional model of the cell site, displayed in a Graphical User Interface (GUI).

7. The modeling method of claim 1, wherein the one or more data acquisition techniques comprise using a fixed or portable camera to capture the first data and the second data.

8. The modeling method of claim 1, wherein the one or more location identifiers comprise at least two location identifiers comprising Global Positioning Satellite (GPS) and GLObal NAvigation Satellite System (GLONASS).

9. The modeling method of claim 1, wherein the second model is created using the first model as a template for expect objects at the cell site.

10. A modeling system adapted for detecting changes in or at a cell site, the modeling system comprising:

a network interface and a processor communicatively coupled to one another; and

memory storing instructions that, when executed, cause the processor to

obtain first data regarding the cell site from a first audit performed using one or more data acquisition techniques and obtain second data regarding the cell site from a second audit performed using the one or more data acquisition techniques, wherein the second audit is performed at a different time than the first audit, wherein the one or more data acquisition comprise using an Unmanned Aerial Vehicle (UAV) to fly about the cell site to capture the first data in a first flight and the second data in a second flight which is at the different time from the first flight, and wherein the UAV is constrained in each flight to capture the first data and the second data utilizing a zone indicator on the ground at the cell site to launch from a same location and same orientation in both the first flight and the second flight, wherein the orientation defines which direction the UAV is facing at launch and landing, and wherein the first data and the second data each comprise one or more location identifiers associated therewith;

process the first data to define a first model of the cell site using the associated one or more location identifiers and process the second data to define a second model of the cell site using the associated one or more location identifiers;

compare the first model with the second model to identify the changes in or at the cell site; and

cause performance of one or more actions based on the identified changes comprising maintenance to correct the identified changes.

11. The modeling system of claim 10, wherein the identified changes are associated with cell site components installed on a cell tower at the cell site, and wherein the one or more actions comprises any of maintenance, licensing with operators, and removal.

12. The modeling system of claim 10, wherein the identified changes are associated with physical surroundings of the cell site.

13. The modeling system of claim 12, wherein the identified changes comprise any of degradation of gravel roads, trees obstructing a cell tower, physical hazards at the cell site, and mechanical issues with the cell tower or a shelter at the cell site.

14. The modeling system of claim 10, wherein the first data and the second data are obtained remotely, without a tower climb.

15. The modeling system of claim 10, wherein the first model and the second model each comprise a three-dimensional model of the cell site, displayed in a Graphical User Interface (GUI).

16. The modeling system of claim 10, wherein the one or more data acquisition techniques comprise using a fixed or portable camera to capture the first data and the second data.

17. The modeling system of claim 10, wherein the one or more location identifiers comprise at least two location identifiers comprising Global Positioning Satellite (GPS) and GLObal NAvigation Satellite System (GLONASS).

18. A non-transitory computer readable medium includes instructions that, when executed, cause one or more processors to perform the steps of:

obtaining first data regarding the cell site from a first audit performed using one or more data acquisition techniques and obtaining second data regarding the cell site from a second audit performed using the one or more data acquisition techniques, wherein the second audit is performed at a different time than the first audit, wherein the one or more data acquisition comprise using an Unmanned Aerial Vehicle (UAV) to fly about the cell site to capture the first data in a first flight and the second data in a second flight which is at the different time from the first flight, and wherein the UAV is constrained in each flight to capture the first data and the second data by utilizing a zone indicator on the ground at the cell site to launch from a same location and same orientation in both the first flight and the second flight, wherein the orientation defines which direction the UAV is facing at launch and landing, and wherein the first data and the second data each comprise one or more location identifiers associated therewith;
